Emotion responsivity, social cognition, and functional outcome in schizophrenia

Social functioning deficits have long been a defining feature in schizophrenia, but relatively little research has examined how emotion responsivity influences functional outcome in this disorder. The goal of the current study was to begin to elucidate the relationships between emotion responsivity, social cognition, and functional outcome in schizophrenia. Participants were 40 outpatients diagnosed with schizophrenia or schizoaffective disorder according to the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) and 40 controls. Each participant completed measures of emotion responsivity, social cognition (both emotion and social perception), and functional outcome. Individuals with schizophrenia demonstrated somewhat reduced emotion responsivity for positive and negative stimuli, as well as deficits in both social cognition and functional outcome, in comparison with controls. Additionally, results indicated that both social perception and emotion responsivity were positively correlated with functional outcome. Importantly, the relationship of emotion responsivity to functional outcome was not mediated by social perception and showed a significant relationship to functional outcome independent of social cognition. This finding suggests that emotion responsivity is an important factor in understanding functional outcome in schizophrenia.
